Vim li cas zirconia- raws li cov ntawv swb siv hauv steelmaking?
Apr 29, 2026
Nyob rau hauv cov txheej txheem steel smelting, muaj ib feem uas yuav zoo li unremarkable tab sis yog ib qho tseem ceeb heev: lubzirconia-raws li zawv zawg rooj vag phaj. Nws ntsiag to lub xub pwg nyom lub luag haujlwm tseem ceeb ntawm kev tswj cov dej ntws ntawm cov hlau molten, tseem tsis tau paub ntau rau lub ntiaj teb sab nraud. Yog li yog vim li cas steel mills nce xaiv rau zirconia- raws li zawv zawg rooj vag daim hlau? Dab tsi ua rau lawv tshwj xeeb?
Dab tsi yog Sliding Gate Plate
Thaum lub sij hawm steelmaking txheej txheem, ntws ntawm molten hlau los ntawm lub ladle mus rau tundish thiab ces mus rau lub pwm yuav tsum tau ib tug txhim khu kev qha "valve" rau kev tswj. Lub valve no yog qhov zawv zawg qhov rooj kaw lus, thiab qhov tseem ceeb tshaj plaws thiab hnav -ib feem ntawm nws yogzawv zawg rooj phaj.
Lub phaj swb yuav tsum tiv taus:
- Kub siab tshaj 1,600 degree
- Siab - nrawm nrawm los ntawm cov hlau molten
- Tshuaj corrosion los ntawm slag
- Tsis tshua muaj thermal shock
Nyob rau hauv cov xwm txheej zoo li no, cov khoom siv ib txwm siv sijhawm tsuas yog 1-2 siv ua ntej yuav tsum tau hloov. Kev taw qhia ntawm zirconia swb daim hlau tau hloov pauv qhov xwm txheej no.
Cov ntaub ntawv sib piv: Zirconia Slides vs. Traditional Slides
| Qhov taw qhia | Ib txwm Al₂O₃-Carbon Slide Phaj | Zirconia Slide Phaj |
|---|---|---|
| Qhov Kev Pab Cuam Siab Tshaj Plaws | ~ 1500 degree | ~ 1700 degree |
| Lub neej ua haujlwm nruab nrab | 1-2 cua sov | 3-6 cua sov |
| Corrosion Resistance | Nruab nrab | Zoo heev |
| Thermal Shock Stability | Nruab nrab | Superior |
| Hloov zaus | Hloov ib lub tshav kub | Ntau-kub siv tas li |
Kev siv tswv yim
Scenario 1: Nruam Casting txheej txheem
- Thaum lub sijhawm ua haujlwm txuas ntxiv mus ntev, zirconia zawv zawg daim hlau ua rau "ntau- siv lub tshuab hluav taws xob," txo qhov zaus ntawm kev hloov pauv thiab txhim kho kev tsim khoom.
Scenario 2: Tshwj xeeb Steel Smelting
- Stainless hlau, siab- alloy steel, thiab lwm yam ntaub ntawv zoo sib xws tso siab heev xav tau ntawm cov ntaub ntawv refractory; zoo tib yam swb daim hlau yog nquag yaig thiab paug ntawm cov hlau molten. Zirconia swb daim hlau muaj zog tshuaj inertness, tsis txhob kis cov hlau molten, thiab xyuas kom meej lub purity ntawm cov hlau.
Scenario 3: Nquag Pib-Stop Operations
- Rau cov kab ntau lawm nrog tsis tu ncua ntau lawm rhythms uas yuav tsum tau nquag pib - nres cycles, thermal shock resistance ntawm zirconia swb daim hlau yog qhov zoo tshaj plaws, txo qhov kev pheej hmoo ntawm kev raug mob.
Dab tsi yog cov txiaj ntsig ntawm zirconia swb daim hlau rau steel mills?
Kev txuag nqi
Ib lub phaj ua haujlwm ntawm peb, txo qhov yuav tsum tau yuav khoom seem
Txuag sij hawm
Tsis tas yuav tsum tau kaw ntau zaus los hloov cov ntawv swb, tso cai rau ntau cov hlau ntau lawm
Kev kaj siab lug
Tsawg dua qhov tshwm sim ntawm cov hlau xau, ua kom muaj kev nyab xeeb
High - zoo steel
Tsis muaj kab mob ntawm cov hlau molten, uas ua rau ntau dua - cov khoom zoo steel
Ua tsaug rau lawv qhov tshwj xeeb siab -kub tsis kam, zoo thermal shock resistance, thiab superior corrosion kuj,zirconia swb daim hlautau dhau los ua qhov kev xaiv zoo tshaj plaws rau qhov tseem ceeb zawv zawg nozzle Cheebtsam hauv kev tsim cov hlau niaj hnub, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom siab - zoo thiab tshwj xeeb steels.
Yog tias koj tab tom nrhiav rau cov khoom lag luam ruaj khov thiab txhim khu kev qha, thov hu rau peb rau cov qauv thiab cov kev daws teeb meem! Cia zirconia swb daim hlau tiv thaiv koj cov kab ntau lawm steel!
